 Purpose The industrial solution SU-302 is a converter which converts serial data to USB data. For this purpose, the device has one USB 2.0 interface and two serial interfaces: 1. RS-232 (for plug type D-Sub, DE-9) 2. RS-485 (also known as EIA-485; compatible with RS-422/ EIA-422) The SU-302 is connected to a client via the USB interface. Alternatively, the SU-302 can be connected to an industrial USB Deviceserver 'INU-100’ by SEH Computertechnik GmbH. This way, the serial devices which are connected to the SU302 can be accessed via a TCP/IP network or the Internet. The USB interface supplies...

Industrial Solution 'IH-304 USB Hub' The industrial solution IH-304 is a USB hub with four USB 3.0 ports. Up to four USB devices such as the SU-302 can be connected to these USB ports and be used via one single USB connection. This is a most efficient solution for control cabinets with few free USB ports. The IH-304 in turn is connected to a client via the USB interface. Alternatively, the IH-304 can be connected to an industrial USB Deviceserver 'INU-100’ by SEH Computertechnik GmbH (’Industrial Solution 'INU-100 USB Deviceserver'’ 2). This way, the connected USB devices can be accessed via...

 Preparation If you connect a serial device to a client via SU-302, the driver installation is the first step. Then the serial interface will automatically be enumerated as port on the client. The enumeration is dynamic, i.e. the serial interface receives the next available port number. Thus it is also client-specific. The serial device will keep the port number even if it is removed occasionally but connected back to the same physical USB interface. To identify the port numbers that the serial devices connected via SU-302 receive from the client, you must note down which port numbers are already...
